> Abstract:
> Garbage Collection (GC) liberates the programmer from having to call malloc
> and free. More importantly GC saves the programmer from having to debug
> their mistakes when using malloc and free. Unfortunately the details of how
> GC works are often a black box. This talk will start with a tour of all of
> the GC algorithms currently available in OpenJDK. We'll discuss how they
> work, their strengths and weaknesses, and which class of applications they
> were developed for. We'll work our way through serial gc, parallel gc,
> concurrent mark and sweep, and g1. We'll make the case for why we need all
> of them and just one more GC algorithm, Shenandoah.
> 
> Shenandoah is a parallel and concurrent GC algorithm designed for
> applications with 100gb+ heaps and tight pause time constraints. It's the
> first GC algorithm targeting OpenJDK which compacts the live objects while
> the Java threads are running. We'll describe the algorithm itself, the
> implementation details, and the optimizations needed to achieve good
> performance. We'll present performance numbers and give a demo that
> visualizes Shenandoah.

Roman Kennke is a long time free Java (and Software) activist, originally involved in GNU Classpath since 2004, later participated in opening OpenJDK and since then is regular contributor to several parts of OpenJDK (AWT/Swing, general class library, lately Hotspot). After finishing Diploma in 2007 he was employed by aicas, who are building a hard realtime capable Java VM. During 2009 and 2010 worked for Sun Microsystems on Java Webstart. After a short period as contractor for JP Morgan, he's now a Prinipal Software Engineer at Red Hat, where he used to work on Thermostat, the Zero and Shark port of OpenJDK, and currently on the Shenandoah GC.
